ENHERTU is a specifically engineered HER2 directed antibody drug conjugate (ADC) being jointly developed and commercialized by Daiichi Sankyo and AstraZeneca (LSE/STO/Nasdaq: AZN).

Validation confirms that the application is complete and commences the scientific review process by the EMA’s Committee for Medicinal Products for Human Use. This application is based on data from the DESTINY-Lung02 phase 2 trial presented at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) 2022 Congress and the DESTINY-Lung01 phase 2 trial published in The New England Journal of Medicine with updated data also presented at ESMO (Free ESMO Whitepaper) 2022.

"ENHERTU is the first HER2 directed medicine shown to have a clinically meaningful tumor response in patients with previously treated HER2 mutant metastatic non-small cell lung cancer based on the results of the DESTINY-Lung02 and DESTINY-Lung01 trials," said Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo. "As there are no approved therapies targeting HER2 mutant non-small cell lung cancer in Europe, we look forward to working closely with the European Medicines Agency to potentially bring a new treatment option to these patients."

About DESTINY-Lung02

DESTINY-Lung02 is a global, randomized phase 2 trial evaluating the safety and efficacy of ENHERTU in patients with HER2 mutant metastatic NSCLC with disease recurrence or progression during or after at least one regimen of prior anticancer therapy that must have contained a platinum-based chemotherapy. Patients were randomized 2:1 to receive ENHERTU 5.4 mg/kg (Cohort 1; n=102) or ENHERTU 6.4 mg/kg (Cohort 2; n=50).

The primary endpoint of the trial is confirmed objective response rate (ORR) as assessed by blinded independent central review (BICR). Secondary endpoints include confirmed disease control rate (DCR), duration of response (DoR) and progression free survival (PFS) assessed by investigator and BICR, investigator-assessed overall survival (OS) and safety. DESTINY-Lung02 enrolled 152 patients at multiple sites, including Asia, Europe, Oceania and North America. For more information about the trial, visit ClinicalTrials.gov.

About DESTINY-Lung01

DESTINY-Lung01 is a global phase 2, open-label, two-cohort trial evaluating the efficacy and safety of ENHERTU (5.4 mg/kg or 6.4 mg/kg) in patients with HER2 mutant (cohort 2, n=91) or HER2 overexpressing (cohort 1 and 1a, n=90) (defined as immunohistochemistry (IHC) 3+ or IHC 2+) unresectable or metastatic non-squamous NSCLC relapsed from or refractory to standard treatment or for which no standard treatment is available.

The primary endpoint of the trial is confirmed ORR by independent central review (ICR). Key secondary endpoints include DoR, DCR, PFS, OS and safety. DESTINY-Lung01 enrolled 181 patients at multiple sites, including Asia, Europe and North America. For more information about the trial, visit ClinicalTrials.gov.

About HER2 Mutant NSCLC

Lung cancer is the second most common form of cancer globally, with more than two million cases diagnosed in 2020.1 In Europe, lung cancer is the third most commonly diagnosed cancer with more than 477,000 cases diagnosed in 2020.2 Lung cancer is also the leading cause of cancer-related deaths in Europe, with nearly 400,000 deaths reported in 2020.2 Prognosis is particularly poor for patients with metastatic NSCLC as only approximately 8% will live beyond five years after diagnosis.3

HER2 is a tyrosine kinase receptor growth-promoting protein expressed on the surface of many types of tumors, including lung, breast, gastric and colorectal cancers. Certain HER2 (ERBB2) gene alterations (called HER2 mutations) have been identified in patients with non-squamous NSCLC as a distinct molecular target, and occur in approximately 2% to 4% of patients with this type of lung cancer.4,5 While HER2 gene mutations can occur in a range of patients, they are more commonly found in patients with NSCLC who are younger, female and have never smoked.6 HER2 gene mutations have been independently associated with cancer cell growth and poor prognosis, with an increased incidence of brain metastases.7 Next-generation sequencing has been utilized in the identification of HER2 (ERBB2) mutations.8,9

Although the role of anti-HER2 treatment is well established in breast and gastric cancers, there were no approved HER2 directed therapies in NSCLC prior to the accelerated U.S. Food and Drug Administration (FDA) approval of ENHERTU in unresectable or metastatic HER2 mutant NSCLC.10,11

On January 4, 2023 Orano Med, a clinical stage radiopharmaceutical company, reported that the first patient has been dosed in a Phase 1 trial of the alpha radioligand therapy with lead-212, 212Pb-GRPR, in patients with advanced solid tumors that express gastrin-releasing peptide receptor (GRPR) (Press release, Orano Med, JAN 4, 2023, View Source [SID1234625852]). 212Pb-GRPR is the first targeted alpha therapy (TAT) targeting GRPR, a protein located on the surface of cells that is highly expressed in prostate cancer, lung cancer, breast cancer and other solid tumors.

"Dosing the first patient in our Phase I 212Pb-GRPR clinical trial is a key development milestone for Orano Med in our strategy to develop a pipeline of alpha radiopharmaceuticals targeting difficult to treat cancers," said Julien Dodet, Chief Executive Officer. "The short-range cancer cell killing capabilities of alpha-emitting radioisotopes could mean there is limited toxicity to surrounding healthy cells. Based on promising preclinical results with 212Pb-GRPR, we believe that this first alpha therapy targeting GRPR could significantly improve outcomes for cancer patients who have exhausted other therapies."

212Pb-GRPR is being evaluated in an ongoing, multi-center, single arm, non-randomized, open-label basket trial that will enroll approximately 30 patients with advanced solid tumors. It includes a dose escalation phase followed by an expansion phase. The primary endpoint is to evaluate the safety and tolerability of 212Pb-GRPR. Exploratory efficacy endpoints include objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) using RECIST v1.1 criteria. Additional information about the trial, which is recruiting patients, can be found on clinicaltrials.gov: NCT 05283330.

"We are convinced that targeted alpha therapies, such as 212Pb-GRPR, are the future of radiopharmaceutical therapies, providing an increased cytotoxic potential against cancer cells and the ability to improve treatments in areas of high unmet needs. We were excited about the success of recent beta emitters but believe that alpha radiopharmaceutical therapies will be the next more effective game changer, which will advance the field significantly," said Michael Morris, MD, Founder & Medical Director of Advanced Molecular Imaging and Therapy, the specialist center where the first patient was dosed.

About Targeted Alpha Therapy

Targeted alpha therapy (TAT) relies on a simple concept: combining the ability of biological molecules to target cancer cells with the short-range cell-killing capabilities of alpha-emitting radioisotopes. Alpha decay consists of the emission of a helium nucleus (alpha particle) together with very high linear energy transfer and a range emission of only few cell layers, resulting in irreparable double strand DNA breaks in cells adjacent only to area of alpha emission. This approach results in an increased cytotoxic potential toward cancer cells while limiting toxicity to nearby healthy cells. As a result, alpha emitters are considered as the most powerful payloads to be found for targeted therapies.

About GRPR

Gastrin-releasing peptide receptor (GRPR) is a G-protein-coupled receptor of the family of bombesin receptors. Its ligand, gastrin-releasing peptide (GRP), is a peptide that regulates numerous physiologic functions of the gastrointestinal and central nervous systems, and is overexpressed in a number of cancers, such as prostate, breast, and lung. Oncology research has made tremendous progress in recent years in treatment of these cancers. However, in the 2020’s, around 25,000 patients are expected to be diagnosed with metastatic prostate cancer in the United States, with an average 5-year survival rate of 30%. In breast cancer, around 50,000 patients are expected to have metastatic tumors, with an average 5-year survival rate of 27%.

On January 4, 2023 -SURGE Therapeutics (SURGE) reported that the U.S. Food & Drug Administration (FDA) has accepted its Investigational New Drug (IND) application to proceed with a Phase 1/2a study of its intraoperative immunotherapy, SURGERx with resiquimod (STM-416), for prevention of recurrence and/or progression after transurethral resection of bladder tumor (TURBT) in patients with non-muscle invasive bladder cancer (NMIBC) who were previously diagnosed with high-grade disease and experience recurrence (Press release, SURGE Therapeutics, JAN 4, 2023, View Source [SID1234625851]).

"Receiving IND clearance to advance our intraoperative immunotherapy platform into a Phase 1/2a trial in our first indication represents an important milestone as we continue to advance our pipeline," said Michael Goldberg, Ph.D., CEO & Founder of SURGE. "Surgery is presently a physical intervention only, and we believe that it should be a biochemically therapeutic intervention as well. We are excited about the prospects of our novel approach and how it can potentially improve the standard of care for cancer patients in this critical context."

"SURGE’s injectable biodegradable hydrogel enables extended, localized release of various cancer immunotherapies at the site of surgical tumor resection. We look forward to working with Michael and his team at SURGE on this initial Phase 1/2a study to advance their lead intraoperative immunotherapy candidate, STM-416, in patients with recurrent bladder cancer to improve post-resection outcomes," said Seth P. Lerner, M.D., Professor of Urology and holds the Beth and Dave Swalm Chair in Urologic Oncology, in the Scott Department of Urology, Baylor College of Medicine.

SURGE’s proprietary hydrogel has been shown in preclinical studies to reduce post-surgical recurrence and metastasis, which account for 90 percent of cancer-related deaths and have been linked to the immune suppression caused by surgery. Reprogramming the body’s response to surgery from immunosuppressive to immunostimulatory can trigger the patient’s immune system to destroy both local and distal residual cancer cells, reducing recurrence and improving survival.

The SURGERx platform is designed to improve the efficacy and safety of immunotherapy treatment, concentrating the effective dose where and when it can yield tremendous impact. It also potentially increases the number of addressable patients for highly potent molecules that are currently limited to treatment of accessible lesions via intratumoral injection.

On January 4, 2023 TAE Life Sciences (TLS), a biological-targeted radiation therapy company developing next-generation boron neutron capture therapy (BNCT), and AIVITA Biomedical, Inc. (AIVITA), a biotech company specializing in innovative stem cell applications, repoted a partnership to address an unmet need in glioblastoma treatment (Press release, TAE Life Sciences, JAN 4, 2023, View Source [SID1234625850]). Acquiring significant amounts of quality glioblastoma tissue samples has long been a barrier in developing novel cancer therapeutics, with samples often plagued by misleading signals such as dead cells, normal cells and extracellular matrix. The enriched glioblastoma tumor initiating cells (TICs) provided by AIVITA may become targets for novel boron target drugs for future BNCT treatments.

"We are thrilled to partner with AIVITA and leverage their ability to identify, isolate and expand high-purity populations of target cell types for therapeutic and diagnostic application," said Bruce Bauer, PhD, CEO of TAE Life Sciences. "This partnership underscores the potential that TAE Life Sciences’ next generation targeted boron drugs and low-energy accelerator-based neutron source holds as a treatment for patients living with the most difficult to treat cancers."

Under the terms of the partnership, AIVITA will provide TICs isolated and expanded from glioblastoma bulk tumors in sufficient quantities as cryopreserved live cell lines to be used by TAE Life Sciences for therapeutic target identification. Among the tumor targets to be identified are cancer biomarkers and biomarkers discovered through genomic analysis that may be novel or unique to an individual patient.

"Advancements in biomarker capture and identification remain an elusive but critical step in improving cancer care," said Hans S. Keirstead, PhD, CEO of AIVITA Biomedical. "I believe this merging of our two leading-edge technologies will lead to meaningful progress in that effort."
